Plotalot makes it easy to create live charts and place them on your site. You must be able to write the SQL queries to retrieve the data you want to plot, but if you can do that, Plotalot will take the data and use the Google Visualization API to produce line graphs, scatter graphs, bar charts, or pie charts of your data, with numerous formatting options. Plotalot does all the hard work for you. These pie charts are drawn live from the Joomla database of this site. Hover your mouse over them:

This chart takes data from the log table generated by our FlexiContactPlus component.

This chart takes data from the Joomla article table, using the query "Select title, hits From jos_content Order By hits Desc Limit 10"

Using the free Plotalot component you can display any number of charts on your site. This page uses the Plotalot Plugin to include charts in an article, which gives you full control of the page layout.

This graph shows monthly downloads of our MiniCalendar Module, which has separate downloads for Joomla 1.5 and 1.6+.

Old Plotalot

Plotalot now uses the Google Visualization API. Older versions of Plotalot used the Google Charts API which is now deprecated. Upgrading to "New Plotalot" is straightforward and fully explained in the user guide. We no longer support the Google Charts API version.

At the front end, Plotalot is completely language independent. Charts appearing on the site are entirely configured by you.

At the back end, Plotalot can be translated into any language by adding a language file. New translations are welcome and will be added to the product. The following languages are currently included, but most are in need of some updating.

English French Italian Russian Dutch German
